Took the MW apart via removing the three screws on the sides and the screws on the back(some nut had put tamper proof torex with a pin in the center to stop me from removing them, vice grips did the job). Pretty easy fix when found out there were three micro switches and used ohm meter to find defective switch problem.

We just popped the replacement parts in. By the way, Sears that sells the Kenmore, the make of our microwave, didn't have the parts we needed online. I was very pleased with my Chat experience with RobinC from your website. She located the parts I needed and even arranged the payment. Great service!
